Tadler Law

What Tadler Law does

Tadler Law LLP is a privately held, women-owned and managed boutique litigation firm founded in June 2019 by Ariana J. Tadler and A.J. de Bartolomeo after leaving Big Law. Headquartered in Manhasset, New York with a second office in San Francisco, the firm maintains a national practice with attorneys licensed in NY, NJ, CA, and CT. It is WBENC-certified as a Women's Business Enterprise and operates as a limited liability partnership.

The firm's core services span class action litigation (securities fraud, data breaches, consumer fraud, antitrust), complex business and commercial disputes, employment matters (discrimination, harassment, equal pay, wrongful termination), and a specialized eDiscovery practice that supports both its own cases and outside matters. Its eDiscovery capability is anchored by Ariana Tadler's authorship of The Jumpstart Outline (Third Edition) published by The Sedona Conference and her past role as Chair of The Sedona Conference's Working Group 1 Steering Committee on Electronic Document Retention and Production.

Tadler Law operates a dual revenue model: contingent-fee plaintiff representation (where the firm advances costs and recovers fees only from settlement proceeds) and traditional hourly billing for business disputes, employment matters, and consulting engagements. It positions itself as a cost-effective alternative to large firms while pricing at premium boutique rates, evidenced by consistent Band 1 Chambers USA rankings from 2021 onward and consecutive Legal 500 recognition. The firm is also an approved Third Party Certifier for the SBA WOSB Federal Contracting Program, opening government contracting access. In July 2025, the founding partners joined Kaplan Fox & Kilsheimer LLP as Of Counsel while continuing to operate Tadler Law independently.

Revenue model

1. Contingent Fee Representation: Tadler Law LLP sometimes represents plaintiffs on a contingent basis, typically advancing the court costs and expenses of litigation, and obtaining its fees and reimbursement of costs and expenses from any recovery. If not successful, the firm does not hold the client responsible for fees, costs or expenses unless otherwise agreed.
2. Traditional Hourly/Fee-for-Service: Provides sophisticated legal representation for business disputes, commercial litigation, employment matters, and legal consulting services with cost-effective billing practices typical of boutique litigation firms.
